i am trying to create pdf using pdfbox. i am storing EditText data as html in Sqlite DB.

now i am retrieving data from sqliteDB and creating pdf of that. this data is having marathi language as well as english language.

i am using NotoSerifDevanagari-Bold font and have added it to assets folder. from there i am accessing this font into code. but i am getting error. please find my code and error below.

AssetManager assetManager;
PDFBoxResourceLoader.init(getApplicationContext());
File FilePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
assetManager = getAssets();
PDDocument document = new PDDocument();
PDPage page = new PDPage();
document.addPage(page);
PDFont font = PDType0Font.load(document, assetManager.open("notoserifdevanagaribold.ttf"));
PDPageContentStream contentStream;
// Define a content stream for adding to the PDF
contentStream = new PDPageContentStream(document, page);
Cursor data = mDatabaseHelper.getDataByDeckname(deckname);
StringBuilder builder=new StringBuilder();
while (data.moveToNext()) {
    String front_page_desc = data.getString(3);
    String back_page_desc =  data.getString(4);
    contentStream.beginText();
    contentStream.setNonStrokingColor(15, 38, 192);
    contentStream.setFont(font, 12);
    contentStream.newLineAtOffset(100, 700);
    contentStream.showText(Html.fromHtml(front_page_desc).toString());
    contentStream.endText();
    contentStream.beginText();
    contentStream.setNonStrokingColor(15, 38, 192);
    contentStream.setFont(font, 12);
    contentStream.newLineAtOffset(100, 700);
    contentStream.showText(Html.fromHtml(back_page_desc).toString());
    contentStream.endText();

document.save(path);
document.close();
ERROR
W/System.err: java.lang.IllegalArgumentException: No glyph for U+000A in font NotoSerifDevanagari-Bold
I tried so many examples for above error but i am not able to fix the issue. this error i am getting on contentStream.showText(Html.fromHtml(front_page_desc).toString()); line. can someone please help me on above.
                if i am replacing contentStream.showText(Html.fromHtml(front_page_desc).toString()); with contentStream.showText(" TEsting content page back"); then also i am getting same error.

                'contentStream.showText(" TEsting content page back"); then also i am getting same error.' - as there appears to be no U+000A character in that string, that is hard to believe.

As per this link U+000A is the Unicode for new line. Any font will fail if you try to render it.
In order to avoid such error you can try something like this:
 String[] lines = text.split("\\n");
        for (String line : lines) {
            if (!line.isBlank()) {
                contentStream.showText(line);
               // add new line here if you want to
